Nemo is Latin for "no one". Nemo is, the Latin rendering of Ancient Greek Outis, the pseudonym adopted by Odysseus, in Greek mythology—a ruse employed to outwit the CyclopsPolyphemus; this appears to be the intended meaning, since in The Mysterious Island, when addressed by Cyrus Harding as Captain Nemo, he replies, "I have no name!" Nothing concerning his past is revealed in Twenty Thousand Leagues Under the Sea, except his dislike of imperialism and the apparent loss of his family in the past. In The Mysterious Island, Captain Nemo identifies himself as Prince Dakkar, son of the Hindu raja of Bundelkhand, a descendant of the Muslim Sultan Fateh Ali Khan Tipu of the Kingdom of Mysore, famous for the Anglo-Mysore Wars and Mysorean rocket technology. After the Indian Rebellion of 1857, in which Dakkar lost his family and his kingdom, he devoted himself to scientific research and developed the Nautilus, wherein he and a crew of followers cruise the seas, they gather bullion from various shipwrecks in the oceans, most notably the wrecks of the Spanish treasure fleet in Bay of Vigo, sunk during the Battle of Vigo Bay.

He claims to have no interest in the affairs of the world above, but he intervenes to aid the oppressed, such as by giving salvaged treasure to participants in the Cretan Revolt against the island's Turkish rulers and by saving a Ceylonese or Tamil pearl hunter from a diving accident, or by saving the castaways from drowning in Twenty Thousand Leagues Under the Sea and covertly protecting another set of castaways in The Mysterious Island. Like many actual Indian princes of the era, Nemo had a European or English education, in which he spent his youth studying and touring Europe. In his first meeting with Professor Aronnax and his companions, they speak to him in French, English and German. Aronnax comments that Nemo's French was perfect, relies on his intuition and knowledge of ethnology to infer that he was from southern latitudes; the Nautilus's library and art collection reveal Nemo to be familiar with European culture and arts. Further, he was an accomplished player of the organ. Nemo is said to have died of old age, on board the Nautilus, at Dakkar Grotto on Lincoln Island in the South Pacific.

Funeral rites were administered by Cyrus Harding, one of the castaways protected by Nemo himself, his vessel was submerged in the waters of the grotto. Nemo's character in the novels is seen through the observations of Professor Pierre Aronnax, the narrator of Twenty Thousand Leagues Under the Sea, when Nemo is about forty years of age and described as a reticent man and swarthy in appearance, with a straight nose and wide-set eyes. In The Mysterious Island, the aged Captain Nemo sports a long white beard, he avoids dry land, except, as with Antarctica and desert islands. In keeping with his contempt for the nations of the surface, he uses no products that are not marine in nature, be it food, furnishing, or tobacco. Little is revealed about his political opinions except an maniacal hatred of oppression, with which he identifies all the imperialistic nations of the world, he therefore identifies himself with those oppressed, be they Cretans rising against the Turks, Ceylonese pearl divers, or black whales attacked by cachalots.

When Professor Aronnax alleges that Nemo violates maritime and international law by sinking warships, Nemo responds that he is defending himself from his attackers, that the laws of the world on the surface no longer apply to him. In one scene, Nemo exclaims: On its surface they can still exercise their iniquitous claims, battle each other, devour each other, haul every earthly horror, but thirty feet below sea level, their dominion ceases, their influence fades, their power vanishes! Ah, live! Live in the heart of the seas! Here alone lies independence! Here I recognize no superiors! Here I'm free! Nemo is devoted to his crew and grieves when one is killed in the giant squid attack in the Caribbean Sea, or after a midnight encounter with a surface ship, he shows the same compassion in his treatment of the castaways in The Mysterious Island, retains a strong attachment to his deceased wife and children. Though short-tempered, he expresses his anger, he is a man of immense courage, in the forefront of every activity, from releasing the Nautilus from the Antarctic ice to fighting squid in the Caribbean.

Jean-Gaston Tremblay was a traditionalist Catholic religious leader and self-proclaimed pope, with the name Gregory XVII. Tremblay was born on September 1928 in Rimouski, Quebec, his father was a lumberjack. Raised as a Catholic, he moved to Montreal at 16. In 1952 he received permission to form his own community, which he called the Congregation of Jesus and Mary; the community moved from town to town for years, before settling in St. Jovite, in Mont-Tremblant, Quebec, in 1958. In 1961, Tremblay met Michel Collin, leader of the Apostles of Infinite Love, who had proclaimed himself pope with the title Clement XV, Tremblay merged his community with the Apostles of Infinite Love; the following year Collin ordained him a priest and soon afterwards consecrated. The group attracted traditional Catholics unhappy with the Second Vatican Council. Only consisting of men, by the late 1960s it included whole families; this prompted the Social Welfare Court of Saint-Jérôme to rule. Seventeen children were taken and handed over to social workers, but Tremblay went into hiding with 55 others, leading him to be listed as one of the ten most wanted men in Quebec.

In September 1968, Tremblay claimed that God had elevated him to the papacy, superseding Collin, with the title Pope Gregory XVII. Eight months Collin acknowledged him as pope. Tremblay linked his papacy with the prophecy of Our Lady of La Salette. Over the following 40 years, Tremblay was the subject of numerous police investigations into charges of kidnapping, illegal detention and child abuse. One former member filed a civil suit for $2.5 million in 2001. Tremblay had served six months in prison in 1977 for defying an order to hand over the boy and his sister to the authorities. In 2001, Tremblay and two others were charged with multiple counts of abuse dating back more than 30 years, but the case was dropped. Tremblay died on December 31, 2011, at a hospital in Sainte Agathe, Quebec
